Apple Issues Fix and Pauses Older iOS Updates After Telstra 000 Glitch on Legacy iPhones

Apple issued a fix, with older-branch updates paused to protect emergency-call reliability.

Overview

  • WA Police and Telstra warned that some older iPhones temporarily could not make or receive calls on Telstra, including 000, before authorities said the issue was resolved after roughly 12 hours.
  • Apple paused the rollout of iOS 18.7.4, 16.7.13, 15.8.6, and 12.5.8 worldwide while investigating the fault; iOS 26.2.1 remained available and was not implicated.
  • The problem was tied to iPhone 8, 8 Plus and X devices updated to iOS 16.7.13 on Telstra, with some users reporting a complete loss of cellular service until the fix.
  • By Thursday afternoon, Apple released a patch that restores connectivity for the affected Telstra devices, delivered via updated carrier settings after connecting to Wi‑Fi.
  • Optus and TPG/Vodafone reported no impact on their customers, and the episode renewed scrutiny of Triple Zero resilience following earlier emergency-call failures.
